 Tokai Pharmaceuticals, Inc. 

255 State Street, 6th Floor 
 Boston, MA 02109 

Attn: Jodie Morrison 
  

	Re:	Equity Financing Commitment 

 Ladies and Gentlemen: 

Reference is made to that certain Share Purchase Agreement (the “Share Purchase Agreement”), dated as of December 21, 2016, by
and among Tokai Pharmaceuticals, Inc. (“Tokai”), Otic Pharma, Ltd. (“Otic”) and the Shareholders of Otic (the “Shareholders”) pursuant to which Tokai will purchase from the Shareholders, and the
Shareholders will sell to Tokai, 100% of the outstanding share capital of Otic, thereby making Otic a wholly-owned subsidiary of Tokai (the “Acquisition”). Capitalized terms not otherwise defined herein shall have the meanings
ascribed to them in the Share Purchase Agreement. 
 This letter agreement is being delivered to Tokai by each “Equity Investor”
set forth on Annex A hereto (each such person or entity being referred to herein as an “Equity Investor,” and, collectively, the “Equity Investors”) in connection with the execution of the
Share Purchase Agreement by Tokai. 
 1. Commitments. 

(a) This letter agreement confirms the commitment to Tokai of each Equity Investor, on a several (and not joint or joint and several) basis
and subject to the conditions set forth herein, to purchase (or cause a Permitted Assignee (as defined below) to purchase), at the Closing, shares of Tokai Common Stock, par value $0.001 per share (the “Common Stock”), for the
aggregate purchase price set forth opposite such Equity Investor’s name on Annex A (such amount, with respect to each Equity Investor, its “Commitment”) pursuant to a Stock Purchase Agreement in substantially the form
attached hereto as Exhibit A, as modified in accordance with Sections 1(b) and 1(d) (the “Purchase Agreement”). 

(b) Concurrent with the execution by each Equity Investor of this letter agreement, each Equity Investor shall deliver to Tokai its signature
page to the Purchase Agreement. Each Equity Investor hereby agrees and authorizes Tokai to attach the signature page to the Purchase Agreement and agrees that, at such time as Tokai has attached the signature page to the Purchase Agreement, it shall
become a party to and be bound by the Purchase Agreement as a “Purchaser” thereunder. The Purchase Agreement shall be executed and delivered by Tokai and the Equity Investors or other investors agreed to by Tokai and Otic on or prior to
January 31, 2017 and shall, unless expressly provided to the contrary in the Purchase Agreement, provide for the purchase and sale of the Common Stock at a price equal to $1.11 per share (subject to adjustment for stock splits and similar
recapitalization events). The Purchase Agreement may be modified prior to its execution and delivery with the prior written consent of Tokai and Equity Investors representing a majority of the Commitment. 







 (c) The obligation of each Equity Investor (together with its Permitted Assignees) to fund its
Commitment, and of Tokai to issue the Common Stock to each Equity Investor at the closing under the Purchase Agreement, is subject only to: (i) the terms of this letter agreement; and (ii) the satisfaction or waiver of the conditions to
closing under Section 7 of the Purchase Agreement. 
 (d) Notwithstanding anything herein to the contrary, the amount of a given Equity
Investor’s Commitment may be reduced upon the agreement of Tokai and Otic upon execution of the Purchase Agreement, provided that the aggregate investments under the Purchase Agreement of the Equity Investors and other investors approved
hereunder shall equal or exceed the aggregate Commitments initially set forth on Annex A. In the event of such a reduction of an Equity Investor’s Commitment, the Equity Investor’s obligations hereunder shall be extinguished upon the
closing under the Purchase Agreement to the extent, and only to the extent, of such reduction. 
 2. Termination. Each Equity
Investor’s obligation to fund its Commitment will terminate automatically and immediately upon the earlier to occur of: (a) the closing under the Purchase Agreement; and (b) the valid termination of the Share Purchase Agreement.
Additionally, upon its execution and delivery, the Purchase Agreement shall supersede this letter agreement and set forth the terms under which the Equity Investor is obligated to purchase shares of Tokai common stock. Upon valid termination of this
letter agreement as to any Equity Investor, such Equity Investor shall not have any further obligations or liabilities in respect of its Commitment hereunder; provided, however, that such termination shall not affect any obligations of
the Equity Investors under the Purchase Agreement. 
 3. Assignment; Amendments and Waivers; Entire Agreement. 

(a) The rights and obligations of Tokai under this letter agreement may not be assigned or delegated (whether by operation of law, merger,
consolidation or otherwise) by Tokai without the prior written consent of each Equity Investor. Except as provided herein, the rights and obligations of each Equity Investor under this letter agreement may not be assigned or delegated (whether by
operation of law, merger, consolidation or otherwise) by such Equity Investor without the prior written consent of Tokai. Any attempted assignment in violation of this Section 3(a) shall be null and void and of no force or effect.
Notwithstanding the foregoing, each Equity Investor may assign all or a portion of its obligations to fund its Commitment to one or more of its affiliated investment funds (including any alternative investment vehicle) that is advised by the
investment manager of such Equity Investor or to any Affiliate of such Equity Investor, in each case to the extent such assignee agrees in writing to be bound by the terms of this letter agreement, delivers to Tokai it signature page to the Purchase
Agreement and can accurately make the representations and warranties set forth in Section 5 of the Purchase Agreement (a “Permitted Assignee”). No assignment permitted pursuant to the foregoing sentence of this Section 3(a)
shall relieve any Equity Investor of its Commitment obligations hereunder except to the extent such obligations are actually fulfilled by any such affiliated entity. This letter agreement may not be amended or otherwise modified except by an
instrument signed by each of the parties hereto. 

  
 2 








 (b) This letter agreement constitutes the entire agreement and supersedes all prior agreements
and understandings, both written and oral, among or between Tokai and the Equity Investors with respect to the subject matter hereof. 
 4.
Enforcement; Damages. 
 (a) Notwithstanding anything that may be expressed or implied in this letter agreement, no person (other
than Tokai, Otic, the Equity Investors and their Permitted Assignees, if any) shall have any obligation hereunder and this letter agreement is not intended to, and shall not, confer upon any third party any rights or remedies hereunder.
Notwithstanding anything to the contrary in this letter agreement, none of Tokai’s creditors shall have any right to cause Tokai to enforce this letter agreement. 

(b) Each Equity Investor and each other party hereto hereby agrees that: (i) the agreements and obligations of each Equity Investor
herein are not enforceable by any other Equity Investor; and (ii) under no circumstances shall an Equity Investor (or any of its Affiliates or Permitted Assignees) be liable hereunder for any special, incidental, consequential, indirect or
punitive damages to any person, including Tokai, any other Equity Investor, or any of their respective Affiliates or equity holders. 
 5.
Incorporation by Reference. 
 (a) Private Placement. The Equity Investors acknowledge that the offering and sale of the
Common Stock will be exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended. Accordingly, the provisions of Section 5 of the Purchase Agreement are incorporated herein by reference. 

(b) Miscellaneous Provisions. The following Sections of the Purchase Agreement are incorporated herein by reference: Sections 13.1
(Waiver and Amendments), 13.5 (Independent Nature of Purchasers’ Obligations and Rights), 13.6 (Governing Law), 13.7 (Counterparts), 13.9 (Entire Agreement) and 13.10 (Payment of Fees and Expenses).

 Exhibit A 

Form of Stock Purchase Agreement 

TOKAI PHARMACEUTICALS, INC. 

STOCK PURCHASE AGREEMENT 

This Stock Purchase Agreement (“Agreement”) is made as of
[                ] [    ], 201[    ] (the “Effective Date”), by and among Tokai Pharmaceuticals, Inc., a
Delaware corporation (the “Company”), each of those persons and entities, severally and not jointly, listed as a Purchaser on the Schedule of Purchasers attached as Exhibit A hereto (the “Schedule of
Purchasers”). The persons and entities listed as Purchasers on the Schedule of Purchasers are hereinafter collectively referred to herein as “Purchasers” and each individually as a “Purchaser.” 

BACKGROUND 
 A. On
December     , 2016, the Company entered into a Share Purchase Agreement with Otic Pharma, Ltd. (“Otic”) and its shareholders (as amended from time to time, the “Otic Share Purchase Agreement”),
pursuant to which the Company has agreed to issue shares of its Common Stock (the “Otic Acquisition Shares”) to the shareholders of Otic in consideration for the acquisition of 100% of the issued and outstanding capital stock of
Otic, whereupon Otic will become a wholly-owned subsidiary of the Company (the “Otic Acquisition”). 
 B. The closing of
the transactions contemplated under the Otic Share Purchase Agreement is conditioned upon, among other things, the approval of the issuance of the Otic Acquisition Shares by the stockholders of the Company at a special meeting of stockholders. 

C. The Company is entering into this Agreement with the Purchasers to provide for the offering and sale of Common Stock, conditioned upon, and
subject to, the closing of the Otic Acquisition under the Otic Share Purchase Agreement. 
 AGREEMENT 

In consideration of the mutual covenants contained in this Agreement, and for other good and valuable consideration, the receipt of which is
hereby acknowledged, the Company, and each Purchaser (severally and not jointly) hereby agree as follows: 
 SECTION 1. AUTHORIZATION OF SALE OF THE
SHARES. 
 The Company has authorized the sale and issuance of [9,009,009] shares of its Common Stock, par value $0.0001 per share (the
“Common Stock”), on the terms and subject to the conditions set forth in this Agreement. The shares of Common Stock sold hereunder at the Closing (as defined below) shall be referred to as the “Shares.” 

SECTION 2. AGREEMENT TO SELL AND PURCHASE THE SHARES. 

(a) Sale of Shares. At the Closing (as defined in Section 3), the Company will sell to each Purchaser,
and each Purchaser will purchase from the Company, the number of Shares set forth opposite such Purchaser’s name on the Schedule of Purchasers at a purchase price of $1.11 per Share (subject to appropriate adjustment for stock splits,
stock dividends, recapitalizations and similar transactions affecting the Common Stock). The aggregate purchase price for the Shares purchased by each Purchaser is set forth opposite such Purchaser’s name on the Schedule of Purchasers. 







 (b) Separate Agreement. Each Purchaser shall severally, and not jointly, be liable
for only the purchase of the Shares that appear on the Schedule of Purchasers that relate to such Purchaser. The Company’s agreement with each of the Purchasers, is a separate agreement, and the sale of Shares to each of the Purchasers is a
separate sale. The obligations of each Purchaser hereunder are expressly not conditioned on the purchase by any or all of the other Purchasers of the Shares such other Purchasers have agreed to purchase. 

SECTION 3. CLOSING AND DELIVERY. 

(a) Closing. The closing of the purchase and sale of the Shares (which Shares are set forth in the Schedule of Purchasers)
pursuant to this Agreement (the “Closing”) shall be held immediately following the satisfaction or waiver of the closing conditions set forth in Sections 6 and 7, including the closing of the Otic Acquisition , with the Closing
to occur at the offices of the Company, or on such other date and at such other place as may be agreed to by the Company and the Purchasers (the “Closing Date”). At or prior to the Closing, each Purchaser shall execute any related
agreements or other documents required to be executed hereunder, dated on or before the Closing Date. 
 (b) Issuance of the Shares at the
Closing. At the Closing, the Company shall issue or deliver to each Purchaser evidence of a book entry position evidencing the Shares purchased by such Purchaser hereunder, registered in the name of such Purchaser, or in such nominee
name(s) as designated by such Purchaser, representing the number of Shares to be purchased by such Purchaser at such Closing as set forth in the Schedule of Purchasers against payment of the purchase price for such Shares. The name(s) in which the
Shares are to be issued to each Purchaser are set forth in the Purchaser Questionnaire and the Selling Stockholder Notice and Questionnaire in the form attached hereto as Appendices I and II (the “Purchaser
Questionnaire” and the “Selling Stockholder Questionnaire,” respectively), as completed by each Purchaser. The Purchaser Questionnaire shall be provided to the Company in connection with the execution of this Agreement and
the Selling Stockholder Questionnaire shall be provided to the Company no later than the Closing Date. 
 (c) Delivery of the Registration
Rights Agreement. At or before the Closing, the Company and each Purchaser shall execute and deliver the Registration Rights Agreement in the form attached hereto as Appendix III (the “Registration Rights Agreement”),
with respect to the registration of the Shares under the Securities Act of 1933, as amended (the “Securities Act”). 
 SECTION 4.
REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY. 
 Except as set forth on the Schedule of Exceptions delivered to the
Purchasers concurrently with the execution of this Agreement (the “Schedule of Exceptions”) or as otherwise described in the SEC Documents (as defined below), which disclosures qualify these representations and warranties in their
entirety, the Company hereby represents and warrants as of the date hereof, and covenants with, the Purchasers as follows: 
 (a)
Organization and Standing. The Company: (a) has been duly incorporated and is validly existing as a corporation in good standing under the laws of Delaware with full corporate power and authority to own or lease, as the case may
be, and to operate its properties and conduct its business as presently conducted, and (b) is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction which requires such qualification,
except in the case of clause (b) above, to the extent that the failure to be so 







 
qualified or be in good standing would not reasonably be expected to result in (i) a material adverse effect on the validity or enforceability of this Agreement, (ii) a material adverse
effect on the condition (financial or otherwise), earnings, business or properties of the Company, or (iii) a material adverse effect on the Company’s ability to perform in any material respect its obligations under this Agreement (any of
clauses (i), (ii) or (iii), a “Material Adverse Effect”). The Company has no subsidiaries.  
 (b) Corporate
Power; Authorization. The Company has all requisite corporate power and authority, and has taken all requisite corporate action, to execute and deliver this Agreement and the Registration Rights Agreement (as defined below, and together with the
Agreement, the “Transaction Documents”), and, subject to any required stockholder approval under the rules and regulations of NASDAQ, to sell and issue the Shares and carry out and perform all of its obligations under the
Transaction Documents. Each Transaction Document constitutes the legal, valid and binding obligation of the Company, enforceable in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws relating to or affecting the enforcement of creditors’ rights generally, (ii) as limited by equitable principles generally, including any specific performance and (iii) with respect to the Registration
Rights Agreement, as rights to indemnity or contribution may be limited by state or federal laws or public policy underlying such laws. 

(c) Issuance and Delivery of the Shares. The Shares have been duly authorized and, when issued and paid for in compliance with
the provisions of this Agreement, will be validly issued, fully paid and non-assessable and free of any security interest, lien, pledge, claim, charge, escrow, encumbrance, right of first offer, right of first
refusal, preemptive right, mortgage, indenture, security agreement or other restriction (“Encumbrance”) other than restrictions on transfer under the Transaction Documents, applicable state and federal securities laws and
Encumbrances created by or imposed by the Purchasers. Assuming the accuracy of the representations made by each Purchaser in Section 5, the offer and issuance by the Company of the Shares is exempt from registration under
the Securities Act. 
 (d) SEC Documents; Financial Statements. The Company has filed in a timely manner all documents that the
Company was required to file with the Securities and Exchange Commission (the “Commission”) under Sections 13, 14(a) and 15(d) the Securities Exchange Act of 1934, as amended (the “Exchange Act”), since becoming
subject to the requirements of the Exchange Act. As of their respective filing dates (or, if amended prior to the date of this Agreement, when amended), all documents filed by the Company with the Commission since January 1, 2016 (the
“SEC Documents”) complied in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission promulgated thereunder. None of the SEC Documents as of their respective dates contained
any untrue statement of material fact or omitted to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading. The financial
statements of the Company included in the SEC Documents (the “Financial Statements”) present fairly the financial condition, results of operations and cash flows of the Company as of the dates and for the periods indicated, comply
as to form with the applicable accounting requirements of the Exchange Act and have been prepared in conformity with United States generally accepted accounting principles applied on a consistent basis throughout the periods involved (except as
otherwise noted therein). PricewaterhouseCoopers LLP, who have certified certain financial statements of the Company delivered their report with respect to the audited financial statements and schedules included in the SEC Documents, are independent
public accountants with respect to the Company within the meaning of Regulation S-X. 







 (e) Capitalization. The authorized capital stock of the Company is as set forth in the SEC
Documents. As of the Effective Date, there are no shares of Preferred Stock issued and outstanding and there are [                    ] shares of
Common Stock issued and outstanding, of which no shares are owned by the Company. There are no other shares of any other class or series of capital stock of the Company issued or outstanding. The Company has no capital stock reserved for issuance,
except that, as of the Effective Date, there are (i) [                    ] shares of Common Stock reserved for issuance pursuant to the
Company’s stock incentive plans, of which [                    ] shares are issuable upon the exercise of stock options outstanding on the date
hereof and [                    ] shares are issuable upon the vesting of restricted stock units outstanding on the date hereof, (ii)
[                    ] shares of Common Stock reserved for issuance pursuant to the Company’s employee stock purchase plan and (iii)
[                    ] shares of Common Stock reserved for issuance upon the exercise of outstanding warrants. There are no bonds, debentures, notes
or other indebtedness having general voting rights (or convertible into securities having such rights) (“Voting Debt”) of the Company issued and outstanding. Except as stated above, and except for the obligations to issue the
Otic Acquisition Shares under the Otic Share Purchase Agreement, there are no existing options, warrants, calls, subscriptions or other rights, agreements, arrangements or commitments relating to the issued or unissued capital stock of the Company,
obligating the Company to issue, transfer, sell, redeem, purchase, repurchase or otherwise acquire or cause to be issued, transferred, sold, redeemed, purchased, repurchased or otherwise acquired any capital stock or Voting Debt of, or other equity
interest in, the Company or securities or rights convertible into or exchangeable for such shares or equity interests or obligations of the Company to grant, extend or enter into any such option, warrant, call, subscription or other right,
agreement, arrangement or commitment. The issuance of Common Stock or other securities pursuant to any provision of this Agreement will not give rise to any preemptive rights or rights of first refusal on behalf of any natural person or legal
entity (each a “Person”) or result in the triggering of any anti-dilution rights. There are no agreements or arrangements under which the Company is obligated to register the sale of any of its securities under the Securities Act.

 (f) Litigation. No action, suit or proceeding by or before any court or governmental agency, authority or body or any
arbitrator involving the Company or its property is pending or, to the best knowledge of the Company, threatened that will have a Material Adverse Effect, whether or not arising from transactions in the ordinary course of business. 

(g) Governmental Consents. No consent, approval, order or authorization of, or registration, qualification, designation,
declaration or filing with, any federal, state, or local governmental authority on the part of the Company is required in connection with the consummation of the transactions contemplated by this Agreement or the Registration Rights Agreement except
for (a) the approval by the NASDAQ Stock Market of the listing of the Shares and (b) the filing of one or more registration statements and all amendments thereto with the Commission as contemplated by the Registration Rights Agreement.

 (h) No Default or Consents. Neither the execution, delivery or performance of the Transaction Documents by the Company nor
the consummation of any of the transactions contemplated thereby (including, without limitation, the issuance and sale by the Company of the Shares) will conflict with, result in a breach or violation of, or imposition of any lien, charge or
Encumbrance upon any property or assets of the Company pursuant to, (i) the certificate of incorporation or by-laws of the Company, (ii) the terms of any indenture, contract, lease, mortgage, deed of
trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which the Company is a party or bound or to which its or their property is subject, or (iii) any statute, law, rule, regulation,
judgment, order or decree applicable to the Company of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or any of its properties, except in the case of clauses
(ii) and (iii) above, for any conflict, breach or violation of, or imposition that would not have a Material Adverse Effect. 







 (i) No Material Adverse Change. Since September 30, 2016, there have not been any
material adverse changes in the assets, liabilities, financial condition, business or operations of the Company from that reflected in the Financial Statements except for the continued incurrence of losses and changes in the ordinary course of
business which have not had, either individually or in the aggregate, a Material Adverse Effect. 
 (j) No General Solicitation.
Neither the Company nor any Person acting on its behalf, has engaged in any form of general solicitation or general advertising (within the meaning of Regulation D promulgated under the Securities Act) in connection with the offer or sale of the
Shares.  
 (k) No Integrated Offering. Neither of the Company or any Person acting on its behalf has, directly or
indirectly, made any offers or sales of any security or solicited any offers to buy any Company security, under circumstances that would adversely affect reliance by the Company on Section 4(a)(2) of the Securities Act or require registration of any
of the Shares under the Securities Act or cause this offering of the Shares to be integrated with prior offerings by the Company for purposes of the Securities Act. 

(l) Sarbanes-Oxley Act. There is and has been no failure on the part of the Company and any of the Company’s directors or officers,
in their capacities as such, to comply in any material respect with any applicable provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith, including, without limitation, Section 402
relating to loans. 
 (m) Intellectual Property. The Company owns, possesses, licenses or has other rights to use, on reasonable
terms, all patents, patent applications, trade and service marks, trade and service mark registrations, trade names, copyrights, licenses, inventions, trade secrets, technology, know-how and other intellectual

parties to any Company Intellectual Property, other than as licensed by the Company. To the knowledge of the Company, there is no infringement by third parties of any Company Intellectual Property. There is no pending or, to the Company’s

patent, trademark, copyright, trade secret or other proprietary rights of others. The Company is not aware of any facts required to be disclosed to the U.S. Patent and Trademark Office (“USPTO”) which have not been disclosed to the
USPTO and which would preclude the grant of a patent in connection with any patent application of the Company Intellectual Property or would form the basis of a finding of invalidity with respect to any issued patents of the Company Intellectual
Property that would have a Material Adverse Effect.

compliance with applicable NASDAQ continued listing requirements. There are no proceedings pending or, to the Company’s knowledge, threatened against the Company relating to the continued listing of the Common Stock on NASDAQ and the Company

the conduct of its business as it relates to a Company Product and as described in the SEC Documents (collectively, “Authorizations”) and such Authorizations are valid and in full force and effect and the Company is not in violation
of any term of any such Authorizations; (iii) the Company has not received any written notice of adverse finding, warning letter or other written correspondence or notice from the U.S. Food and Drug Administration (the “FDA”)

hearing, enforcement, investigation, arbitration or other action from any governmental entity or third party alleging that any Company Product, operation or activity related to a Company Product is in violation of any Applicable Laws or
Authorizations or has any knowledge that any such governmental entity or third party is considering any such claim, litigation, arbitration, action, suit, investigation or proceeding, nor, to the Company’s knowledge, has there been any
noncompliance with or violation of any Applicable Laws by the Company that would reasonably be expected to require the issuance of any such written notice or result in an investigation, corrective action, or enforcement action by the FDA or similar
governmental entity with respect to a Company Product; (v) the Company has not received written notice that any governmental entity has taken, is taking or intends to take action to limit, suspend, modify or revoke any Authorizations or has any

records, claims, submissions and supplements or amendments as required by any Applicable Laws or Authorizations and that all such reports, documents, forms, notices, applications, records, claims, submissions and supplements or amendments were
complete, correct and not misleading on the date filed (or were corrected or supplemented by a subsequent submission). To the Company’s knowledge, neither the Company nor any of its directors, officers, employees or agents, has made, or caused
the making of, any false statements on, or material omissions from, any other records or documentation prepared or maintained to comply with the requirements of the FDA or any other governmental entity. 







 (s) Taxes. The Company has filed all tax returns that are required to be filed or has
requested extensions thereof (except in any case in which the failure so to file would not have a Material Adverse Effect, whether or not arising from transactions in the ordinary course of business) and has paid all taxes required to be paid by it

as of the date of this Agreement and will be true and correct as of the Closing and the effective date of the Registration Statement; provided, that the Purchasers shall be entitled to update the information in the Selling Stockholder
Questionnaire by providing notice thereof to the Company before the effective date of such Registration Statement. 
 xii. Such Purchaser
understands that no United States federal or state agency, or similar agency of any other country, has reviewed, approved, passed upon, or made any recommendation or endorsement of the Company or the purchase of the Shares.

investment decision with respect to the Shares was made (if an entity) are located at the address immediately below such Purchaser’s name on its signature page hereto. 

xvii. Such Purchaser (including any person controlling, controlled by, or under common control with such Purchaser, as the term
“control” is defined pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and its implementing regulations (the “HSR Act”)) in connection with the consummation of the transactions contemplated
by this Agreement will not be required to and will not complete a filing with the U.S. government pursuant to the HSR Act. 
 (b) Other than
consummating the transactions contemplated hereunder, such Purchaser has not, nor has any person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any purchases or sales, including all
“short sales” as defined in Rule 200 of Regulation SHO under the Exchange Act (but shall not be deemed to include the location and/or reservation of borrowable shares of Common Stock) (“Short Sales”), of the securities of
the Company during the period commencing as of the time that such Purchaser was first contacted by the Company or any other person regarding the transactions contemplated hereby and ending immediately prior to the Effective Date. Notwithstanding the
foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment
decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment
decision to purchase the Shares covered by this Agreement. Other than to other persons party to this Agreement, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the
existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to the identification of the availability
of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future. 
 (c) Purchaser
understands that nothing in this Agreement or any other materials presented to Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. Purchaser has consulted such legal, tax and investment
advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Shares. 







 (d) Legends. 

(a) Purchaser understands that, until such time as the Shares have been sold pursuant to the Registration Statement or the Shares may be sold
pursuant to Rule 144 under the Securities Act (“Rule 144”) without any restriction as to the number of securities as of a particular date that can then be immediately sold, the book entry notations evidencing the Shares may bear one
or more legends in substantially the following form and substance: 
 “THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE U.S.
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER SECURITIES LAWS.
NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT
OR PURSUANT TO A TRANSACTION WHICH IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION, IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS, AND IN THE CASE OF A TRANSACTION EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION, UNLESS THE
COMPANY HAS RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT AND SUCH OTHER APPLICABLE LAWS.” 

In addition, book entry notations representing the Shares may contain: 

(i) Any legend required by the laws of the State of California, including any legend required by the California Department of Corporations.

 (ii) Any legend required by the blue sky laws of any other state to the extent such laws are applicable to the sale of such Shares
hereunder. 
 (iii) A legend regarding affiliate status of the Purchasers set forth in Schedule 1 hereto, in the form included therein. 

(b) The Company agrees that at such time as such legend is no longer required under this section, it will, no later than three business days
following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing Shares, and if such Shares are certificated, issued with a restrictive legend, together with such representations and covenants
of such Purchaser or such Purchaser’s executing broker as the Company may reasonably require in connection therewith, deliver or cause to be delivered to such Purchaser a book entry position representing such shares that is free from any legend
referring to the Securities Act. The Company shall not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this section. To the extent that certificates or
book entry positions are issued representing the Shares, such certificates or book entry positions subject to legend removal hereunder shall be transmitted by the transfer agent of the Company to the Purchasers by crediting the account of such
Purchaser’s prime broker with the Depository Trust Company (“DTC”). All costs and expenses related to the removal of the legends and the reissuance of any Shares shall be borne by the Company. 







 (c) The restrictive legend set forth in this section above shall be removed and the Company shall
issue a certificate or book entry position without such restrictive legend or any other restrictive legend to the holder of the applicable shares upon which it is stamped or issue to such holder by electronic delivery with the applicable balance
account at DTC or in physical certificated shares, if appropriate, if (i) such Shares are registered for resale under the Securities Act (provided that, if the Purchaser is selling pursuant to an effective registration statement
registering the Shares for resale, the Purchaser agrees to only sell such Shares during such time that such registration statement is effective and such Purchaser is not aware or has not been notified by the Company that such registration statement
has been withdrawn or suspended, and only as permitted by such registration statement); (ii) such Shares are sold or transferred pursuant to Rule 144 (if the transferor is not an affiliate of the Company); or (iii) such Shares are eligible for
sale without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such securities and without volume or
manner-of-sale restrictions. Subject to receipt of such representations, and covenants as are contemplated hereby, following the earlier of (i) the effective date
of the Registration Statement or (ii) Rule 144 becoming available for the resale of the Shares, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to the Shares and without
volume or manner-of-sale restrictions, the Company shall issue to the Company’s transfer agent the instructions with respect to legend removal consistent with this
section. Any fees (with respect to the transfer agent, the Company’s counsel or otherwise) associated with the issuance of such opinion or the removal of such legend shall be borne by the Company. 

(e) Restricted Shares. Purchaser understands that the Shares are characterized as “restricted securities” under the
federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such Shares may be resold without registration under the Securities Act
only in certain limited circumstances. In this connection, such Purchaser represents that it is familiar with Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act. 

(f) Exculpation Among Purchasers. Purchaser acknowledges that it is not relying upon any other Purchaser, or any officer, director,
employee, agent, partner, member or affiliate of any such other Purchaser, in making its investment or decision to invest in the Company. Purchaser agrees that neither any Purchaser nor the respective controlling Persons, officers, directors,
partners, agents, or employees of any Purchaser shall be liable to any other Purchaser for any action heretofore taken or omitted to be taken by any of them in connection with the purchase of the Shares.

 SECTION 10. ADDITIONAL AGREEMENTS OF THE PARTIES. 

(a) NASDAQ Listing. The Company will use commercially reasonable efforts to continue the listing and trading of its Common Stock on
NASDAQ and, in accordance, therewith, will use commercially reasonable efforts to comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of such market or exchange, as applicable. 

(b) Termination of Covenants. The provisions of Section 10.1 shall terminate and be of no further force and
effect on the date on which the Company’s obligations under the Registration Rights Agreement to register or maintain the effectiveness of any registration covering the Registrable Securities (as such term is defined in the Registration Rights

 (c) Integration. The Company shall not, and shall use its commercially reasonable efforts to ensure
that no affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer
or sale of the Shares in a manner that would require the registration under the Securities Act of the sale of the Shares to the Purchasers, or that will be integrated with the offer or sale of the Shares for purposes of the rules and regulations of
any trading market such that it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction.

provisions of the existing confidentiality and non-use obligations of the parties hereto (including the existence and terms of this transaction) (such obligations, the “Confidentiality
Obligations”). Each Purchaser understands and acknowledges that the Commission currently takes the position that coverage of short sales of shares of the Common Stock “against the box” prior to effectiveness of a resale

proxy statement seeking stockholder approval of the issuance and sale of the Shares and (iii) the filing of final Transaction Documents with the Commission; and (b) as otherwise required by law or Nasdaq regulations , provided that to the
extent disclosure is permitted by law or NASDAQ regulations, the Company shall provide the Purchaser with prior notice of such disclosure under this clause (b). As of the time of the filing of the 8-K, the
Company shall not be aware that any Purchaser shall be in possession of any material, non-public information received from the Company, any subsidiary of the Company or any of their respective officers,
directors, employees or agents, pursuant to the transactions contemplated by this Agreement that is not disclosed in the 8-K, press release or other disclosure by the Company that complies with the
requirements of Regulation FD.
 SECTION 11. INDEMNIFICATION. 

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each of the Purchasers and each Person, if any,
who controls any Purchaser within the meaning of the Securities Act (each, an “Indemnified Party”), against any losses, claims, damages, liabilities or expenses, joint or several, to which such Indemnified Party may become subject
under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as
such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based in whole or in part on the inaccuracy in the representations and warranties of the Company contained in this
Agreement or the failure of the Company to perform its obligations hereunder, and will reimburse each Indemnified Party for legal and other expenses reasonably incurred as such expenses are reasonably incurred by such Indemnified Party in connection
with investigating, defending, settling, compromising or paying such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim,
damage, liability or expense arises out of or is based upon (i) the failure of such Indemnified Party to comply with the covenants and agreements contained in Sections 5 and 4 above respecting sale of the Shares, or (ii) the
inaccuracy of any representations made by such Indemnified Party herein. 
 (b) Indemnification by Purchasers. Each Purchaser
shall severally, and not jointly, indemnify and hold harmless the other Purchasers and the Company, each of its directors, and each Person, if any, who controls the Company within the meaning of the Securities Act, against any losses, claims,
damages, liabilities or expenses to which the Company, each of its directors or each of its controlling Persons may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common
law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Purchaser) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated
below) arise out of or are based upon (i) any failure by such Purchaser to comply with the covenants and agreements contained in Sections 5 and 4 above respecting the sale of the Shares unless such failure by such Purchaser is
directly caused by the Company’s failure to provide written notice of a Suspension to such Purchaser or (ii) the inaccuracy of any representation made by such Purchaser herein, in each case to the extent, and will reimburse the Company,
each of its directors, and each of its controlling Persons for any legal and other expense reasonably incurred, as such expenses are reasonably incurred by the Company, each of its directors, and each of its controlling Persons in connection with
investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. No Purchaser shall be liable for the indemnification obligations of any other Purchaser.

 SECTION 13. MISCELLANEOUS. 

(a) Waivers and Amendments. Neither this Agreement nor any provision hereof may be changed, waived, discharged, terminated,
modified or amended with respect to the Company and a Purchaser only with the written consent of the Company and such Purchaser. 







 (b) Headings. The headings of the various sections of this Agreement have been inserted
for convenience of reference only and shall not be deemed to be part of this Agreement. 
 (c) Severability. In case any
provision contained in this Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby. 

(d) Replacement of Shares. If the Shares are certificated and any certificate or instrument evidencing any Shares is mutilated,
lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence
reasonably satisfactory to the Company and the Company’s transfer agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold
harmless the Company and the Company’s transfer agent for any losses in connection therewith or, if required by the transfer agent, a bond in such form and amount as is required by the transfer agent. The applicants for a new certificate or
instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Shares. If a replacement certificate or instrument evidencing any Shares is requested due to a mutilation thereof,
the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement. 

(e) Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein and no action taken by any
Purchaser pursuant hereto, shall be deemed to constitute the Purchaser as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group, or are
deemed affiliates (as such term is defined under the Exchange Act) with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including
without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. 

(f) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents
shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations,
enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be
commenced exclusively in the state and federal courts sitting in New York, New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City and County of New York for the adjudication
of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to
assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby
irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at
the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve
process in any other manner permitted by law. 







 (g) Counterparts. This Agreement may be executed in two or more counterparts, each of
which shall constitute an original, but all of which, when taken together, shall constitute but one instrument, and shall become effective when one or more counterparts have been signed by each party hereto and delivered to the other parties. In the
event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing
(or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile of “.pdf” signature were the original thereof. 

(h) Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto; provided, however, that a Purchaser may not assign its rights and delegate its duties hereunder in whole or in part to an affiliate or to a third party
acquiring some or all of its Shares in a transaction complying with applicable securities laws without the prior written consent of the Company, provided such assignee agrees in writing to be bound by the provisions hereof that apply to Purchasers.

 (i) Entire Agreement. This Agreement and other documents delivered pursuant hereto, including the exhibit and the Schedule
of Exceptions, constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof. 

(j) Payment of Fees and Expenses. Each of the Company and the Purchasers shall bear its own expenses and legal fees incurred on
its behalf with respect to this Agreement and the transactions contemplated hereby. If any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable
attorney’s fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled. 
 (k)
Survival. The representations, warranties, covenants and agreements made in this Agreement shall survive any investigation made by the Company or the Purchasers and the Closing.
